Title: Improvements in or relating to devices for feeding sheets to machines
IPC: B65H3/08
Filed: 1939-04-06
Abstract: 520,368. Feeding sheets. CROSS PAPER FEEDER CO. (1939), Ltd. April 6, 1939. No. 10734. Convention date, May 5, 1938. [Class 100 (i)]  A sheet-feeding device of the kind described in Specification 504,489 for producing a stream of overlapping sheets is constructed without the use of combing wheels or buckling- devices to assist in the separation of the sheets from the pile, and the sheets are separated by means of independently actuated suction devices 81 which raise the rear edge of the top sheet of a pile and carry it rearwardly into contact with registering devices 84. The suction devices 81 are operated by oscillating levers 90, 92, Fig. 6, which act first by means of links 94 to raise the suckers about pivots 100 so as to give the rear edge of the sheet a sharp bend after the nozzle 80 of the sucker has engaged the sheet. Prior to this the pile is controlled by means as in Specification 504,530 to bring the rear edge of the top sheet close to a sheet guide 164, which in conjunction with a guide 166 directs the sheet to the registering fingers 84. The suckers 81 are then rocked to an approximately horizontal position, position 111, Fig. 9, by raising the pivots 100 by means of links 96 assocated with the levers 90, but to prevent a rapid horizontal movement of the sheet due to the straightening of toggle links composed of the suction member 81 and links 160 supported by an oscillating lever 140, the lever 140 is moved clockwise to the position shown in dotted lines, Fig. 9, by a rock bar 148 associated with a bell-crank lever 144, 146 actuated by a cam on a shaft 114 which also carries the cams associated with the levers 90, 92. During this action the pivotal motion of each link 160 is accompanied by an outward movement which is effected by an oscillating cam 194 acting on the hub of the link 160 positively to move this hub axially in an outward direction. The nozzles 80 thus tauten the sheet so that its edge is straight when it engages the registering devices. In a modification of the tautening devices the suckers are moved inwards by cams and move outwards under spring action. The engaging of the registering device 84 by the sheet actuates a pawl 181 which engages a tooth on the rack bar 148 and prevents further movement of the' suction device. As each device 84 is engaged independently, the rear edge of the sheet is finally square with the devices 84. The sheet is finally advanced by an oscillating suction device 82 as in the second modification described in Specification 504,489. Air blasts are used to assist the separation of the sheets. While the suckers engage the pile, the sheets are flapped up by blasts from pipes 252, and when the sheet is raised and bent by the suckers, a blast is directed between the separated sheet and the rest of the pile by an oscillating foot clamp 258, Fig. 2.

As shown, the container has a pair of rigid opposite walls 16 supporting between them a baffle 11, and a pair of flexible opposite walls 19 as of rubber spaced from the baffle so as to provide a film passage. Sockets 13 are provided in the walls 16 to receive the film spool 14, and rollers 9, 12 are mounted above and below the baffle. A rubber tape 23 extends from the spool and round the baffle and the rollers, to a light-trapped slot 20 in one side of the container. In operation, the film backing paper 27 is unrolled until the end of the film appears ; the end of the backing is passed through the slot 20 ; the end of the film is attached by a clip 25 to the end of the tape 23 ; the spool is dropped into the sockets 13 ; the cover 7 is applied ; and the tape 23 and backing strip 27 are then pulled out through the slot 20, thereby drawing the film round the passage between the baffle 16 and the walls 19. The various liquids are introduced through an inlet 8 and drawn off through an outlet 10. Liquid agitation is effected by squeezing the walls 19 and is facilitated by passages 15 through the baffle 16.

Title: Method of producing resistances
IPC: H01B1/24
Filed: 1936-04-17
Abstract: <PICT:0473658/III/1> Apparatus for the manufacture of high ohmic resistances by the deposition of carbon on a suitable insulating former comprise a tubular furnace 1, of diameter slightly larger than the formers, through which the formers are passed in succession in the same direction as a current of hydrocarbon vapour.  A suitable hydrocarbon, e.g. benzol diluted with inert gas is passed through the furnace in excess from inlet 3 and the formers are fed in at mouthpiece 4, which is suitably sealed to prevent leakage of the gas. The first part only of the pipe is heated to decomposition temperature by the heater 2, and the coated formers 5 cool in an atmosphere of the hydrocarbon vapour as they slowly pass through the unheated portion of the tube.  The heated portion of the tube is made sufficiently long to permit the formers to remain in this zone for a sufficient time to ensure a even carbon deposit, and low operating temperatures may also be used.  To equalize the resistance to gas flow of the furnace, the interior of the pipe 1 may be fluted or spirally grooved.

The wire is withdrawn through capillary 16 aided by compressed gas fed at 17 into a container 14 housing the apparatus. When the wire is bonded, wheel 10 is removed from rotor 4 and power from variable transformer 19, Fig. 3, drives motor 4 in the reverse direction for tensioning the wire via a resistance 20 manually varied by spindle 23 operating cam 22 and micro-switch 21 until the leaf spring 6 engaging spool pin 7 flexes and closes a parallel motor circuit through spool 2, spring 6 and contact 8, after which further movement of spindle 23 and cam 2 opens the micro-switch. Tensioning is then further increased by increasing the transformer voltage. Should the bond break, the leaf spring unflexes and opens contact 8 to prevent the motor pulling wire back on to the spool. Bonding may be thermocompression, ultra-sonic or spot welding, and the bond is viewed by microscope for stretching or peeling prior to rupture. The tensioning may be produced by bodily movement of the spool by hydraulic, pneumatic or mechanical means.
